To address the high bending stresses and potential structural failure risks caused by differential settlement at expansion joints during bridge widening projects of straight bridges, this paper proposes an “Adaptive Rebound Displacement Compensation Device”. Existing research primarily focuses on analyzing settlement patterns and passive control standards, with limited attention to active dynamic regulation. Notably, the bending stress induced by new pier settlements can reach 3–5 times that of vehicle loads, posing serious safety concerns. Through theoretical derivation, this study clarifies the relationship between superstructure loss of strength and factors such as pier settlement, device stiffness, friction coefficient, and L-shaped baffle angle, and a comprehensive design framework is established accordingly. Combining numerical simulations, laboratory tests, and field measurements from engineering practices, multiple validation approaches are employed. The simulation results demonstrate that the proposed device can limit deck subsidence to 10–20% of pier settlement height, and experimental outcomes align closely with theoretical predictions. This device has been successfully implemented in a bridge widening project on a highway section in Jiangxi Province. It should be noted that all data presented in the paper are derived from finite element method (FEM) numerical simulations, and there are currently no on-site measurements of the device’s performance. FEM analysis indicates that the device demonstrates certain feasibility for practical engineering applications. Compared to scenarios without the installation of this device, bridge deck displacements can be reduced by approximately 16.5%. By enabling adaptive rebound through self-adjustment mechanisms for settlement compensation, this device significantly alleviates bending stresses at expansion joints, breaking through traditional passive control limitations. This study provides an innovative approach for actively controlling settlement differences in the widening of straight bridges, offering significant implications both at the theoretical and practical levels.

This study investigates the cyclic behavior of reinforced concrete beam–column joints strengthened with hybrid GFRP–steel reinforcement using nonlinear finite element analysis. Six hybrid configurations—defined by varying the percentage of the total longitudinal steel reinforcement area, in the beam, replaced with GFRP bars (0%, 20%, 25%, 33%, 50%, and 100%)—were evaluated in terms of load–displacement hysteresis, stiffness degradation, dissipated energy, and crack development. A multi-criteria decision analysis (MCDA) was employed to quantitatively compare the six configurations. The findings demonstrate the potential of partial GFRP substitution to enhance the seismic performance of reinforced concrete beam–column joints. Full article

This paper investigates the bearing behavior of squeezed branch piles and straight-shaft piles under uplift and combined horizontal–uplift loading in silty clay strata. Utilizing a combined approach of laboratory model tests and numerical simulation, the influence of key parameters, such as the depth of the first branch and branch spacing, on the bearing capacity was systematically analyzed. The results demonstrate that under combined loading, the bearing capacity of squeezed branch piles is significantly superior to that of straight-shaft piles, with double-branch piles outperforming single-branch piles. The bearing capacity increases with the depth of the first branch and the branch spacing, reaching its optimum when the first branch is buried at a depth of 6 d (where d is the straight-shaft pile diameter). This study also reveals a unique mechanical response under combined loading: the load–displacement curves exhibit a “smoothed” characteristic, rendering the traditional inflection point method unsuitable for determining the ultimate bearing capacity. Furthermore, a significant coupled weakening effect exists between horizontal and uplift forces. However, increasing the depth of the first branch (to 6 d) and the branch spacing can effectively mitigate this effect, enhancing the pile’s stability under complex loading conditions. This research provides a crucial basis for the optimized design and application of squeezed branch piles in complex loading environments. Full article

This study investigates the mechanical performance of squeezed branch piles under combined loads (horizontal combined with uplift/compression) in silty clay through model tests. Based on a systematic comparison of the mechanical responses among straight-shaft piles, single-plate piles, and double-plate piles, the load-dependent behavior of branched piles is revealed, and optimized design principles are proposed. The results demonstrate that under horizontal combined loads, squeezed branch piles effectively mobilize soil-arching effects via the bearing plates, leading to significant enhancements in both horizontal and vertical-bearing capacities compared to straight-shaft piles. Double-plate piles exhibit superior overall deformation resistance due to composite confinement; however, an adverse superposition effect at a plate spacing of 2 d may result in a marginally lower capacity. The horizontal capacity of single-plate piles increases with embedment depth, with the axial force peaking at a critical depth of 4 d (embedment depth of first plate). The upper plate plays a dominant role in resisting deformation, consistently carrying 75–105% higher axial force than the lower plate. This research provides important theoretical support and practical references for the design of pile foundations subjected to complex loading conditions. Full article

The acoustic, thermal, and mechanical performances of sawdust-reinforced polyurethane (PU) foam are investigated for different thicknesses and varying mesh sizes. Acoustic properties are explored using a combination of impedance tube testing and mathematical modeling with the Johnson–Champoux–Allard–Lafarge (JCAL) model, a simplified JCAL model and a model of non-uniform cylindrical pores with a log-normal radius distribution (NUPSD). Thermal Insulation and mechanical properties are determined by measuring the effective thermal conductivity (Keff) and by tensile strength tests, respectively. Compared with pure PU foam, the presence of sawdust matches noise reduction coefficients (NRC) and increases sound absorption averages (SAA) by nearly 10%. Increasing thickness and width of backing air gap have the usual effects of improving low- and mid-frequency absorption and shifting resonance peaks toward lower frequencies. As well as superior acoustic performance, samples with Mesh 16 sawdust reinforcement provide both useful insulation (Keff = 0.044 W/mK) and tensile strength (~0.06 MPa), confirming their multifunctionality. Although the JCAL model provides reasonable fits to the sound absorption data, some of the fitted parameter values are unphysical. Predictions of the NUPSD model are relatively poor but improve with sample thickness and after fiber addition. Full article

To investigate the feasibility of utilizing waste rock wool fiber as an additive in asphalt mixtures for resource recycling, this study evaluates and analyzes the performance of asphalt and asphalt mixtures, as well as their environmental benefits. Initially, the properties and mechanisms of modified asphalt mortar are examined under different shapes (powdery rock wool fiber (RWP) and fibrous rock wool fiber (RWF)) and varying rock wool fiber contents (0%, 1%, 2%, 3%, and 4% of matrix asphalt mass). Subsequently, the pavement performances of asphalt mixtures with different RWF contents (0%, 0.1%, 0.2%, 0.3%, and 0.4% of asphalt mixture mass) are compared. The environmental and economic impacts of RWF-modified asphalt mixtures are assessed using the life cycle assessment (LCA) method and the benefit cost analysis (BCA) method. Finally, the carbon property ratio (CPR), an innovative index, is proposed. It comprehensively evaluates the pavement performances and economic benefits of RWF modified asphalt mixtures in relation to carbon emissions (CEs). The results indicate that compared to RWP, RWF primarily functions as an inert fiber stabilizer. It provides a physical reinforcing effect through its three-dimensional network skeleton structure. Both RWP and RWF-modified asphalts exhibit improved performance compared to matrix asphalt. RWF demonstrates superior temperature susceptibility and high temperature performance. The optimal contents for achieving the best high temperature, water stability, and low-temperature crack resistance performances of RWF-modified asphalt mixtures are 0.3%, 0.2%, and 0.2%, respectively. As the RWF content increases, the energy consumption (EC) and CEs during the pavement construction stage slightly rise within an acceptable range, while positive economic benefits also increase. Additionally, the CPR index can comprehensively assess the favorable effects of pavement performances or economic benefits against the adverse effects of CEs. It offers theoretical guidance for the design of optimal rock wool fiber content. Full article

Global climate change has placed a heavy burden on the environment, with building energy consumption gradually emerging as a major environmental stressor. Therefore, energy conservation and emission reduction in buildings have increasingly become key issues of great concern. In regions with hot summers and cold winters, building envelope structures often use insulation materials to facilitate energy efficiency in buildings. Graphite composite insulation material (GCIM), a high-performance building insulation composite material, is composed primarily of graphite polystyrene particles (GPPs), glass microspheres (GMs), cement, and silica fume (SF). The thermal conductivity (TC) is an important parameter that affects its insulation performance. The volume ratios (VRs) of the material components will have a significant impact on its TC. However, there is currently a relative lack of theoretical research on the influencing factors of its TC, and its TC mechanism is not very clear. Therefore, a novel series-parallel alternate heat conduction theoretical model (SPAM) was established in this paper. The theoretical calculation expression for the TC of GCIM was derived using Fourier’s law of heat conduction. Through numerical simulation, three models comprising a total of 60 finite element (FE) models were constructed. The results of the numerical simulation were compared with theoretical calculations to further determine the influence of material component VRs on the TC of GCIM. The research results indicate that in the three established conventional models, the TC of GCIM decreases rapidly in the early stages and then stabilizes later, with a critical point at Ψ1Ψ2=Ψ1Ψ4=5. Within the specified range of VR variations, the value of Ψ1Ψ2 has the greatest impact on the TC performance of GCIM, followed by Ψ1Ψ4, while Ψ1Ψ3 has the smallest impact. The research findings will guide the material composition of the GCIM, reduce their TC, enhance their insulation performance, decrease building energy consumption, and hold high theoretical and practical value. This research will provide a theoretical reference basis for the widespread application of the GCIM in the field of building insulation. Full article

The effective length factor (ELF) of bridge piers, a critical design parameter, is determined by solving the transcendental equation governing stability. Efficient and accurate solutions to these equations under various constraints are essential for automating bridge design software. In this paper, the bridge pier is simplified as an elastically restrained column based on the Timoshenko beam model, and the pier stability equation under general elastic constraints considering shear deformation is derived. By analyzing the distribution patterns of the solutions to the transcendental equations with and without considering shear deformation, a novel two-stage Adaptive Sequential Root Search Method based on bisection algorithm (ASRSBM2s) is proposed to calculate the ELF. In the first stage, the smallest positive root of the transcendental equation without considering shear deformation is first calculated, and the obtained positive root is used to restrict the solution domain of the transcendental equation considering shear deformation in the second stage. Compared with the results of the finite element method (FEM), the proposed algorithm can accurately determine the correct roots of the transcendental equation for various bridge scenarios, and the maximum relative error of the calculated ELF of bridge piers is below 2.5%.

Extrusion-based 3D Construction Printing (3DCP) involves developing novel material mixtures that incorporate local geo-materials. Given that clay minerals and silt are major causes of soil variability, this study focuses on the fine fraction of soil to facilitate purpose-oriented design, classification, and standardization. We begin with an overview of current research in the field and general information about clays. Subsequently, we establish an evaluation methodology, examining various clay–sand mix ratios, along with locally sourced material to gain general insights into the material’s clay-dependent macro-printability characteristics. The findings are then correlated and discussed in relation to the microcharacteristics of the clays, emphasizing the significance of both intraparticle and interparticle swelling for strength and cohesiveness. Factors such as swelling ability, and charge, which may be reflected by pH, are pivotal for strength; while the quantity of clay and its interparticle swelling ability, denoted by the plasticity index (PI), delineate cohesiveness, which is essential for pumpability and extrudability. Furthermore, the presence of organic material and other minerals is observed to have a significant impact on these properties. Full article

There have been beaching events of the marine alga pelagic sargassum in coastal regions of the Caribbean Sea, West African countries, and the north-northeast region of Brazil since 2011. Its presence has caused environmental and socioeconomic impacts while several studies were conducted in order to understand the causes of this phenomenon, as well as alternatives to mitigate its impacts. The objective of this research was to evaluate pelagic sargassum biomass from beaching as a raw material for the manufacture of medium-density multilayer particleboards, aiming for an application that can reduce the impacts generated by the disposal of this seaweed on beaches and landfills. These are composed of 30% sargassum particles in their inner layer and 70% sugarcane bagasse particles on their outer layers, which are bonded with castor-oil-based polyurethane resin. A physical and chemical characterization was carried out in order to evaluate sargassum particles while physical and mechanical tests were carried out in order to evaluate the panels. Results were subsequently compared with indications from different particleboard standards. A life cycle assessment was carried out to complement the feasibility study of these panels and to compare their different manufacturing processes. The multilayer panels met the minimum requirements for physical and mechanical properties established by regulations, indicating that the Sargassum spp. biomass can be used as filling. The life cycle assessment study indicates that sargassum panels produced in the Belém, PA, Brazil, region present lower environmental impacts in four of seven evaluated categories when compared to conventional panels. Given the results obtained, the use of sargassum from beaching events as raw material for panels can be presented as an alternative for reducing social, economic, and environmental impacts in the regions affected by these events.

Uneven settlement of transmission tower foundations can result in catastrophic events, such as tower collapse and line failures, disrupting power transmission operations. To address the challenging repairs caused by uneven foundation settlement of transmission towers, we propose an adjustable foundation bolt (AFB). This paper provides a detailed theoretical analysis of the AFB’s stability and load-bearing capacity, including critical buckling force formulas and maximum normal stress expressions. Finite element simulations confirm the precision of our theoretical formulations. Additionally, we introduce a method using baffles to enhance its load-bearing capacity, analyzing the impact of different numbers of baffles through numerical simulations. The experimental results validate the effectiveness of baffles in enhancing structural load-bearing capacity. The device brings convenience and efficiency to the maintenance of transmission towers.

The utilization of mineralized sandy shredded corn cob (SCC) as a partial replacement for fine aggregate in Portland cement mortars (PM) presents an innovative opportunity for sustainable construction and organic waste reutilization. This study aims to assess the impact of SCC, with granulometric variations G1 and G2, on eight mortar formulations (PM, SCC-G1-5%, SCC-G1-10%; SCC-G2-5%, SCC-G2-10%, SCC-G2-15%, SCC-G2-20%, and SCC-G2-30%) with a consistent water-to-cement ratio of 0.55. Fresh-state properties (flowability, temperature, pH, unit weight, and setting time) and hardened-state characteristics (compressive strength at 4, 7, 14, and 28 days) were evaluated. Notably, flowability decreased by 90% for G2 designs with up to 15% SCC, unit weight decreased by up to 12% with SCC-G2-30%, setting time was delayed, and compressive strength for all SCC mortars up to 20% exceeded 21.9 MPa. In conclusion, the partial replacement of sand with a G2 particle-size distribution of SCC is feasible, with an optimal performance observed in SCC-G2-5%. Full article

Global interest in sustainable building materials is increasing due to growing concerns regarding the environmental impacts of conventional construction materials, particularly fired clay bricks. Compressed Stabilized Earth Blocks (CSEBs) have emerged as a viable, cost-effective, and environmentally sustainable alternative for building construction. The incorporation of waste-derived additives in CSEBs not only addresses waste management challenges but also enhances the functional performance of earthen materials. This study presents a comprehensive synthesis of existing research on the influence of fibers, binders, stabilizers, and production processes on the performance characteristics of CSEBs. A systematic literature review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 guidelines, resulting in the identification and analysis of 256 relevant studies. The selected literature was synthesized using the Theories, Contexts, Characteristics, and Methodologies (TCCM) framework to map research trends and methodological approaches. The review indicates that fiber reinforcement primarily improves flexural strength and thermal performance, while binders significantly enhance compressive strength and erosion resistance. The findings also demonstrate that selected waste materials can partially replace natural soil, provided minimum material and performance standards are satisfied. The study highlights the need for standardized manufacturing guidelines and testing protocols to improve the reliability, scalability, and wider adoption of CSEBs in sustainable building applications.
